Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 850M
IntroThe GeForce GTS 450 1GB has a clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the GeForce GTX 850M, which features a clock frequency of 876 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 450 1GB should theoretically be much better than the GeForce GTX 850M in general. (explain)
Texel RateThe GeForce GTX 850M is much (more or less 40%) better at anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe GeForce GTX 850M is a small bit (about 12%) more effective at AA than the GeForce GTS 450 1GB, and also able to handle higher resolutions more effectively. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
